Description

    TECHNICAL FIELD.
  • The present invention is concerned with wireless communication with field devices using wireless transceivers. In particular it is concerned with configuration of wireless field devices in a distributed control system.
  • BACKGROUND ART
  • In distributed systems with many field devices for interaction with eg an industrial plant or a power plant it is common that each field device needs setup data or configuration data for a sensor and/or actuator comprised in the field device during the commissioning of the system. If a field device must be replaced the new field device needs a copy of this configuration data that was configured during the commissioning of the system.
  • In an industrial installation a distributed control system (DCS) or an industrial control system may be equipped with a large number of field devices. Usually such an industrial installation has one or more control rooms and a computer system which are connected by one or more data networks, such as buses or fieldbuses the field devices. The data network may comprise both wired and wireless links. Field devices may include various types of sensor instrument such as vibration sensors, pressure sensors, temperature gauges, as well as devices that include an actuator such as a valve actuator, a solenoid, a breaker or isolator or on/off switch and the like. Each field device needs to be configured suitably to carry out the chosen function of a individual device. Each field device at a specific location is usually given an identity in the control system or DCS. A wireless field device may also have an identity in a wireless network.
  • Common methods for entering the setup data include use of an Human machine Interface (HMI) on the field device or to connect a laptop pc, whereupon the configuration data may be entered and sent to the field device. However when replacing a device, it is normally not possible to read a copy of the configuration data setup during commissioning from a non-working device. Using the correct setup data is particularly important in wireless networks where a new device needs to act (function) exactly the same as the old device to be accepted without reconfiguring the network.
  • IEEE 1451 is a standard for transducer interfaces. A part of this standard is the definition of Transducer Electronic Data Sheets (TEDS). The TEDS is a memory device attached to the transducer, which stores transducer identification, calibration, correction data, measurement range, and manufacture-related information, etc. This simplifies initial configuration or subsequent replacement of a sensor by retaining in the TEDS memory device information about the sensor type so that a new sensor may be interrogated to give its transducer identification, calibration, correction data etc. as supplied by a manufacturer. The TEDS may also include information in respect of a specific device at a specific location such as an application specific transducer name. However a wireless field device comprising a sensor and/or actuator during commissioning, maintenance or replacement of the field device may also require configuration with information in order for the field device to access the wireless network.

    DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Figure 1a shows as an exemplary practice of an embodiment of the present invention a field device that comprises a base part that is left in place when a second part of the device is removed. Fig 1a shows a field device 9" arranged as first part 1, and a second part 2. The second part 2 is arranged with an antenna 5. The second part 2 is detachable from the first part 1 as indicated by the arrow R.
  • Figure 1b shows a more detailed block diagram of the field device 9". It shows a base part 1 arranged with a memory storage device 3, in the form of a non volatile memory. Base part 1 also includes a sensor 10 or transducer, and may also include an actuator 11. The base part may be arranged with a mechanical or galvanic connection interface.
  • The base part, first part 1, contains a non-volatile memory for the setup and configuration data. The base part may be left in place when a field device has to be replaced. When installing a new field device, it is only necessary to install a second part which replaces the previous second part of the field device. Once connected, the new second part of the field device can read all setup and configuration data from the non-volatile memory in the base part 1.
  • Figure 1b shows the first part 1 connected to a second part 2. The figure shows the second part 2 to include an antenna 5, and a radio transceiver or transmitter 14. The figure also shows a battery 7 arranged to power at least the radio transmitter. A processor 15 and an Input/Output (I/O) interface 19 are shown. The transmitter 14, processor 16 may be arranged on a common circuit board. A data connection 19 is arranged between the processor 16 and a sensor 10 and/or actuator 11 by means of the I/O interface 18, for example as a serial data connection. A data connection 17 is arranged between the I/O interface 18 and the processor 16. The processor 16 sends data to the wireless radio transmitter 14 for transmission. The antenna may be positioned in a predetermined direction to optimize wireless communication with other nodes and/or the DCS.
  • The processor in the second part 2 may read the configuration data stored in the memory storage device 3 by means of a separate interface or by means of a common interface with the I/O interface 18.
  • Figure 2 shows a control system with a wireless data network to which a plurality of field devices 9a, 9m, 9s, 9t are wirelessly connected. The figure shows a distributed control system 50 with a wireless data network 20, a wired fieldbus 23 and a wireless router or gateway 26. The DCS may have one or more wired data networks 25 to which may be connected an industrial controller 24, a central control system computer 28, an operator workstation 29 and an engineering workstation 30. Equipment and monitoring and/or control equipment such as the valve A may be connected, eg by a fieldbus 23 directly to a control system computer 28 or connected via an industrial controller 24 to a control system or DCS.
  • Figure 2 also shows a first field device 9s arranged mounted on a structure such as a stand, a wall or framework or similar in a process installation. A second field device 9a is arranged as an actuator or valve. A third field device 9m is arranged mounted on an electric motor M and the field device 9m may be implemented as a wireless vibration sensor. A fourth wireless field device 9t is shown arranged together with a temperature measuring instrument T. Wireless communication from the field devices to the DCS may be carried out by the field devices communicating directly with the DCS or other control system or communicating via a hub or gateway 26, or by sending transmissions via other field devices such as may be done with a wireless a sensor network WSN.
  • During the initial system commissioning a field device 9 configured by, for example, entering the setup data. This may be carried out on site by connecting to a Human machine Interface (HMI) on the field device or by connecting a portable computer such as a laptop pc, whereupon the necessary configuration data may be entered and sent to the field device, where it is stored (written) to the memory storage device 3 in the base part 1. Configuration information may comprise:
    • a name of the field device at a specific location, an application specific transducer name, or an identity of the field device at a specific location in the DCS control system;
    • a name, identity, address or network identity for the wireless radio network eg 20 that the field device at a specific location shall be connected to;
    • configuration data of a calibration nature to setup a specific sensor, eg a vibration sensor at the specific location with parameters or other information dependent on the actual output specific sensor in the field device.
  • At any time after initial configuration, the second part 2 may be detached from the first part 1 (base) at a specific location. A second part with, for example, a new battery may be attached to the first part at the specific location. In operation, the processor of the second part then reads the configuration data stored in the memory 3 in the first part (base) that was left at the specific location and the field device comprising the original first part a second part connected to it functions in the same way as the original field device at that specific location.
  • The first part 1, the base, is left in place after the second part is detached. The first part may be arranged with a identification device or a location device 8. This may take the form of an RFID (Radio Frequency IDentification) tag or badge. The location device may be arranged for optical reading, such as a machine readable code or a barcode. This is an advantage for locating field devices or sensors arranged in an industrial installation in the oil and gas industry, or in a paper mill, in which there may be hundreds or even thousands of separate devices.
  • Figure 3 shows a schematic flowchart for configuration of field device. It shows:
    • 31 Install a wireless field device at a specific location, that is, to a location with a known name or identity in the DCS;
    • 33 Configure the wireless field device with name of the field device, or application specific transducer name, or identity of the field device in the DCS control system;
    • 34 Calibrate the field device and store parameter / calibration information, when necessary store calibration information, adjustments, set points for the field device;
    • 35a Store the configuration information in memory 3, the base of the field device;
    • 36 Configure the wireless field device for communication with a wireless network with a wireless identity, wireless network address etc.;
    • 35b Store the wireless configuration information in memory 3 at the same time as 35a or else later.
  • Figure 4 shows a schematic flowchart for operating or configuring the field device after changing the second part 2 of the field device. This may be for a battery exchange or eg for maintenance reasons. It shows:
    • 41 Connect a second part 2 to a first part 1 of a field device installed at a specific location;
    • 43 Configuration information for the field device at the specific location is read by processor 16 and/or wireless transceiver 14 in second part 2 from memory 3 storage in first part 1;
    • 45 The wireless field device at the specific location is now configured for operation and for communication with a wireless network 20
  • In a preferred embodiment of the invention a wireless field device in the form of a vibration sensor (9m) is provided.
    A small, autonomous sensor unit 9m is mounted onto a motor, for example an AC motor. The unit comprises a vibration transducer element (accelerometer), analogue filtering, A/D conversion, temporary data storage and wireless communication to a computer of a DCS. The DCS computer performs the necessary data analysis and makes the data available to potential users. Vibration is, however, a most demanding phenomenon to monitor with wireless communication because of the large amount of data (e.g. 4 or 8kB of data) that is needed for the vibration analysis. Most Wireless Sensor Networks (WSN) are used to collect a couple of bytes (e.g. a temperature value) from each node.
  • The sensor unit may be implemented using a processor such as a MSP430F427 microcontroller (MCU) from Texas Instruments. This processor requires low power, has advanced 16 bit sigma-delta A/D converter and an internal 32kB flash memory. The low power results in long battery life. The advanced A/D converter of this processor is used to sample the vibration data with required resolution and sample rate. The flash memory provides for permanent storage of program code and for temporary storage of sampled data.
  • The above MCU processor may be arranged to use an external 32 kHz real time clock arranged such that the processor is in deep sleep (Low Power Mode) most of the time. The clock wakes up the MCU typically once a week (the interval may be configured wirelessly) to sample vibration data. Before sampling, the signal may be filtered in advanced analogue filters adapted to the vibration analysis. The sampled data is first temporarily stored in the MCU flash and then sent over the wireless network using the low throughput that is possible in a typical wireless mesh sensor network. A suitable vibration sensor/transducer or accelerometer is preferably of the MEMS-based piezo-resistive bridge transducer.A pcb-mounted antenna (pcb - printed circuit board) may provide a low cost solution. A ceramic pcb-mounted antenna has been shown to provide a wireless communication range of >25m sensor to sensor in a wireless sensor network.
  • The radio communication to and from the sensor 9m may be handled by a low power transceiver such as a DN2040 transceiver from Dust Networks. This is a system-on-chip transceiver designed for low-power applications. The DN2040 contains a dedicated communication processor, a flash memory and a radio transceiver. The DN2040 may be used with the Time Synchronous Mesh Protocol (TSMP) developed by Dust. The sensor may also be arranged to operate with a WirelessHART standard that is also based on TSMP.
  • The wireless field device 9 may be arranged a node of a wireless LAN, and/or may be another kind of wireless node, running any radio protocol suitable for an industrial milieu, such as any standard issued by the Bluetooth Special Interest Group (SIG), any variation of IEEE-802.11, WiFi, Ultra Wide Band (UWB), ZigBee or IEEE-802.15.4, IEEE-802.13 or equivalent, a WirelessHART standard, or similar.
  • It should be noted that while the above describes exemplifying embodiments of the invention, there are several variations and modifications which may be made to the disclosed solution without departing from the scope of the present invention as defined in the appended claims.
